One Item
The FS 3400A uses KYO TK12 (KYO 87800705) toner cartridge. KYO TK12 yields 10000 pages.
The KYO TK12 cartridge has an approximate yield of 10000 pages.
A "Supply Problem" message on the FS 3400A usually points to a chip-communication hiccup rather than an empty cartridge. Power-cycle the printer (off for 30 seconds, then on), reseat the cartridge until it clicks into place, and gently clean the gold chip contacts with a dry cloth. If the message returns, a replacement KYO TK12 will clear it.
